A popular myth about granite is its (possible) radioactivity. Let's take a closer look at this matter and find out about the radioactivity of granite and other natural stones.
Although it is now mostly in ruins, the unique design and mysterious presence of Stonehenge continues to draw nearly one million visitors each year. They marvel at its grandeur and wish they could have watched it being built and seen it when it was new.
For centuries, Stonehenge has fascinated the peoples of the world and even today, with all our modern wonders, it receives almost a million visitors per year who travel to Salisbury Plain in Wiltshire, England just to spend some time basking in its magic.
The process of natural stone and the “make or buy” in the large production areas of Massa Carrara and Verona (Italy).
The worldwide first quarry of an orbicular granite with spheres diametres ranging from 15 to 18 cm was recently opened in Finland by a netural stone company.
At shops for natural stone, they often seem to sell only two kinds of natural stones – granite and marble. However, the marble tiles for your living room, or the granite countertop for your kitchen may well be some other kind of natural stone.
Granite and marble is expensive, is an often heard assumption. While many years ago this statement was – for most of the materials – true, today it is far less the case.
This is a growing list of thermal properties of natural stones and related materials.
This is a growing list of mechanical properties of natural stones and related materials.
This is a growing list of chemical properties of natural stones and related materials.
The main quarrying methods are drilling and diamond wire cutting. In many cases also chain cutting is used but only for marble or travertine.
What kind of adhesive has which characteristics? Which characteristics of the adhesive are relevant for my gluing?
The gang-saw is more suitable for mass production of thin slabs. In fact, normally there have to be used two (or four, or eight) machines in order to guarantee a continuous material output to the polishing line.

Igneous rocks are formed when molten rock (magma) cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from either the Earth
Granite is a common and widely-occurring group of intrusive felsic igneous rocks that form at great depths and pressures under continents. Granite consists of orthoclase and plagioclase feldspars, quartz, hornblende, biotite, muscovite and minor accessory
Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate). The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pel
Sandstone is an arenaceous sedimentary rock composed mainly of feldspar and quartz and varies in colour (in a similar way to sand), through grey, yellow, red, and white. Since sandstones often form highly visible cliffs and other rock formations, certain c
Gneiss is a common and widely distributed type of rock formed by high grade regional metamorphic processes from preexisting formations that were originally either igneous or sedimentary rocks. Gneissic rocks are coarsely laminated and largely recrystallize
Basalt is an extrusive igneous rock, sometimes porphyritic, and is often both fine-grained and dense. Basalt in the tops of subaerial lava flows and cinders will often be highly vesiculated, imparting a lightweight "frothy" texture to the rock. The term ba
Tuff (from the Italian "tufo" and pronounced "toof") is a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption. The products of a volcanic eruption are (a) volcanic gases, (b) magmas, and (c) steam from water h
Slate is a fine-grained homogeneous sedimentary rock composed of clay or volcanic ash which has been metamorphosed (foliated) in layers (bedded deposits). Slate can be made into roofing shingles ('roofing slates' in the UK) because it has two lines of brea
Quartzite is a hard, metamorphic rock which was originally sandstone. Through heating and pressure usually related to tectonic compression within orogenic belts, the original quartz sand grains and quartz silica cement were fused into one. Pure quartzite i
Travertine is a white concretionary form of calcium carbonate that is usually hard and semicrystalline. It is deposited from the water of mineral springs (especially hot springs) or streams holding lime in solution. Extensive deposits exist at Tivoli, Ital
